Tough And Reliable

I’ve had this hydro flask for a few years now. Let me just say, nothing compares. It keeps ice and water cold. Super easy to dissemble and hand-wash/run through the dishwasher. Plus I’ve sent this thing flying many times and it’s bruised but still in excellent shape. My only teeny tiny complaint would be it doesn’t fit in a cup holder but that doesn’t really bother me too much. Overall excellent performance and better than any other brand I’ve tried.

Color Great, Design Meh

I ordered this bottle for my daughter who is on a roller derby team called the Yetis. Their team color is purple, so the color was great. I love that I found a yeti graphic, but wish I could have ditched the text since it was not really appropriate. Hopefully their personalizations will get more flexible in the future.

Corrosion/rust On Bottom Of The Inside

I’m disappointed that I’m experiencing what appears to be a recurring issue with my Hydro Flask bottles. I replaced my previous bottle, which I had used for over a year, because I began noticing what looked like possible corrosion or rust on the inside bottom. Unfortunately, after only a few months of using my new Hydro Flask, I’m seeing similar discoloration and what appears to be possible corrosion or rust in the same area. I expected better durability and quality from a product like Hydro Flask, especially given its reputation. Seeing this issue develop in two bottles is concerning, particularly because the deterioration is on the interior surface that comes into contact with my drinking water. I’m disappointed to be experiencing this problem again after replacing my original bottle and would appreciate an explanation from Hydro Flask about what might be causing it and whether this is a known issue, especially since I only put wather in my bottle.

Good But

I like the top and I’ve had no leaks. Wasn’t sure I was going to like the straw but I did. Doesn’t seem to keep water as cold as my other Hydroflask containers. I’ve tried ice and putting it in the fridge.

Great Bottles!! Stays Cold!

These are great bottles. We have used them for some time but I dropped mine so many times I needed a new one. We can put ice in these bottles at night and it is still there in the morning! Stays super cold! I customized mine this time getting a black bottle with a grey bottom and cap. I am a huge Raider fan so I picked these colors to go with the emblem I attached. Only problem is, I figured if I get a grey cap, I would get a grey handle. I guess I needed to pick a color for that too. The one they sent me is blue and kind of ruins the look. Other than that, a fantastic bottle!

Warranty Replacement

Old one lost vacuum after 1.5 years. Hydro Flask honored warranty replacement with no problem. Am happy again.
